<h3 class="section">4.9 <code>ld</code> and MSP430</h3>
<p>For the MSP430 it is possible to select the MPU architecture.  The flag &lsquo;<samp>-m [mpu type]</samp>&rsquo;
will select an appropriate linker script for selected MPU type.  (To get a list of known MPUs
just pass &lsquo;<samp>-m help</samp>&rsquo; option to the linker).
</p>
<a name="index-MSP430-extra-sections"></a>
<p>The linker will recognize some extra sections which are MSP430 specific:
</p>
<dl compact="compact">
<dt><code>&lsquo;<samp>.vectors</samp>&rsquo;</code></dt>
<dd><p>Defines a portion of ROM where interrupt vectors located.
</p>
</dd>
<dt><code>&lsquo;<samp>.bootloader</samp>&rsquo;</code></dt>
<dd><p>Defines the bootloader portion of the ROM (if applicable).  Any code
in this section will be uploaded to the MPU.
</p>
</dd>
<dt><code>&lsquo;<samp>.infomem</samp>&rsquo;</code></dt>
<dd><p>Defines an information memory section (if applicable).  Any code in
this section will be uploaded to the MPU.
</p>
</dd>
<dt><code>&lsquo;<samp>.infomemnobits</samp>&rsquo;</code></dt>
<dd><p>This is the same as the &lsquo;<samp>.infomem</samp>&rsquo; section except that any code
in this section will not be uploaded to the MPU.
</p>
</dd>
<dt><code>&lsquo;<samp>.noinit</samp>&rsquo;</code></dt>
<dd><p>Denotes a portion of RAM located above &lsquo;<samp>.bss</samp>&rsquo; section.
</p>
<p>The last two sections are used by gcc.
</p></dd>
